Air Quality Index
The Air Quality Index (AQI) is an indicator of overall air quality that takes into account all of the criteria air pollutants measured within a geographic area. 
The AQI summarizes levels of ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide, which each pose unique risks to human health, into one measure.   There are many dimensions to capturing the health of the natural environment, and air quality is one of the most important. Air quality data was retrieved from the U.S. Environmental Protection Agency.
How is Snohomish County trending?
Snohomish County percentage of days with poor air quality is trending up, but is consistently lower than the Seattle-Tacoma-Bellevue Metro Area.

Water Quality Index
The Water Quality Index (WQI) is a number ranging from 1 to 100. A higher number indicates better water quality. The Water Quality Index condenses a lot of ecological information into one consolidated number for community members and decision makers. It also makes direct comparisons between water bodies possible. Water quality can be degraded by urban development, through the increased presence of impervious surfaces. Quality may also be negatively affected by agricultural production, through the usage of fertilizers and pesticides. Water quality data was retrieved from the Washington State Department of Ecology from sampling site(s) within Snohomish County.
How is Snohomish County doing?

Snohomish County has consistent Water Quality Index on par or above 80, which meets expectations for water quality. The Snohomish County Water Quality Visualization shows water quality readings within Snohomish County.
